So, you have 9.0 compression. I noticed that on Turbo-kits.com that they offer a built bottom end with CR ranging from 8.6, 9.2, 10.5 and 11.5. Being that I only want 600whp, would you recommend the 9.2 CR over the 8.6 CR so that it will make more power at a lower PSI level due to slightly higher compression?

If you are on race gas, the higher comp.ratio setup will make more power...more than likely.
